Fictional sciences refer to scientific concepts and theories that are created for storytelling purposes in literature, film, and other media. These ideas often blend real scientific principles with imaginative elements, allowing authors to explore possibilities beyond current scientific understanding. Examples include time travel, teleportation, and alien life forms. While fictional sciences can inspire real scientific inquiry, they remain distinct from actual science, which relies on empirical evidence and experimentation. Works like science fiction novels and movies often use fictional sciences to engage audiences, prompting them to think about the future and the implications of scientific advancements.
